ˁōŝ - to rise to o's feet, stand up; (sl. to have an erection); to grow; to rise; (plants) to sprout (Gasparini - Morris 2025 208)

The origin is uncertain. Compare probably with Arb. ˁšw ‘to repair, to betake oneself by night’. Cf. also Tgr. ˁassä ‘to fly; to run quickly’ as well as Akk. ašāšu ‘to be worried’. (Kogan 2015:550)
